I don't disagree with you, but with the way they treat these guys when they sign them, there is no point. By the time they strip them down and pound it into them that they don't know how to work, these guys lose confidence and are a shell of themselves.
I think part of what killed Sin Cara was that they guy was clearly nervous and was shitting his pants every time out. Probably because he was told don't do this, don't do that, you don't know how to sell, etc.
If i'm hiring La Sombra, who is 23, tall, has a great body, and is every bit as athletic as Sin Cara, i'm telling him to not change a fucking thing. Go be La Sombra. Over time, he'll adjust as needed. Dolike WCW did and hire a handful and let them work exclusively with each other until they adjust.
But it will never happen. They'd probably take his mask off immediately. Then eliminate half his moveset. Then break him down until he lost his mojo. At that point, you might as well have just hired a white guy who was half as talented, because that's what you end up with.
They should stick with Americans & Euros.
